When disconnecting vacuum hoses, use tags to identify where they should be reconnected.
After completing the job, double check that the vacuum hoses are properly connected. The label under the hood shows the proper layout.
When using a vacuum gauge, never force the hose onto a connector that is too large. Use a step-down adapter for adjustment. Once the hose has been stretched, it may leak air.
